Add wdocker to the EdgeNode container image

[SIR-R0B]

Problem: Currently we ask our users to

apk update

Then, install Node.js
apk add nodejs-lts npm
OR
apk add nodejs if there is no glibc dependency issue

Then Install wdocker

Then install the wdocker CLI and its dependencies globally:
npm install -g @theweave/wdocker
npm install -g @theweave/utils
npm install -g @theweave/group-client
npm install -g @theweave/moss-types

---

Solution, just build these tools into the container so the users don't have to do it.
